Terminal And Connector Inspection

Many malfunctions in the electrical system are caused by poor harness (es) and terminals. Faults can also be caused by interference from other electrical systems and mechanical or chemical damage.
Check the following conditions:
1. Check for damaged harness and terminals: contact resistance, oxidation, bent or broken terminals.
2. Check for poor connection between ECM and component: backed out terminal, improper mating, broken locks and poor terminal to wire connection.
  NOTE: Using a suitable male pin to ensure that contact in sockets is good. The pin should remain in position when pulled gently.
